Definitions

  • This invention relates to an earth ridging apparatus comprising a plurality of plough ridging elements in side-by-side arrangement in a line transverse to the direction in which the apparatus is advanced in operation and secured to a carrying beam or carrying frame, each of said ridging elements having a nose at its underside, which points in the direction of advance, the whole combination of ridging elements and carrying construction being securable to the rear end of a tractor or like vehicle.
  • a similar apparatus is disclosed in Netherlands patent application 6800460.
  • ridging machines are much used for covering potatoes planted in rows with an earth ridge.
  • a rotary cultivator is used for sufficiently loosening the earth to be moved by the ridging apparatus.
  • the ridging elements are spaced some distance apart, and these elements are fixedly connected to a carrying beam.
  • adjustable scraper members Interposed between the ridging elements are adjustable scraper members for imparting a desired shape to the top of the ridge to be formed between adjacent ridging elements.
  • there are "wings" on each ridging element which are adjustable for the apparatus to be adapted to the spacing between the rows of seed potatoes to be covered.
  • the shape and height of the earth ridges being formed are influenced to a certain extent.
  • Netherlands patent 168,683 discloses a rotary cultivator with a ridging apparatus, in which the ridging elements are also combined to a continuous surface. That, however, concerns a ridging apparatus of quite a different type.
  • the ridging elements consist of flat surfaces arranged in V-shape, and disposed so that, in operation, they are dragged along the ground.
  • this is regarded as an advantage relative to a ridging apparatus operating by the plough principle, as does the apparatus according to the present invention.
  • the non-uniform shape of the earth ridges being formed which is mentioned as a disadvantage of ridging apparatus operating by the plough principle, is not produced by the apparatus according to the present invention.
  • a ridging apparatus in which the ridging elements are interconnected to form one whole, each interconnection presenting a first concave continuous surface merging into said ridging elements, facing the direction of advance and forming a ridging edge with the edges of the surfaces between the noses of adjacent ridging elements extending gradually upwards from the plane in which said noses lie, so that, in operation, earth ridges of'a shape dictated by said ridging edges are formed between the noses, the apparatus further comprising means for varying the position of said one whole to suit requirements to set the shape and height of the earth ridges being formed.
  • a cover plate element having a width virtually equal to the width of said one whole of said ridging elements is mounted for rotation about a horizontal shaft arranged along one side of said cover element to extend parallel to the carrying beam or carrying frame, said cover element being spaced some distance ahead of said carrying beam or carrying frame, the height of the cover element being such that, upon rotation of the cover element about said shaft the side of the cover element away from the shaft is in contact with the carrying beam or carrying frame.
  • the cover element when the apparatus is started the cover element is pressed into contact with the carrying beam or the carrying frame to form a closed space.
  • the soil supplied which is moved up and compacted by the ridging elements, cannot be forced backwards over the carrying beam or the carrying frame, so that, as contemplated, all soil is processed to form the earth ridges.
  • the ridging system proper can be readily and easily inspected or cleaned, because the cover element then depends again in the vertical plane, so that the system is accessible from above.
  • said whole to which the ridging elements are interconnected is provided on opposite ends with a vertical sidewall, the plane of which extends virtually in the direction in which the apparatus is advanced when in operation.
  • said whole of said ridging elements is bounded at the top front side to a carrying beam provided with cross-beams or cross-bars directed forwardly from its opposite ends said cross-beams or cross-bars being at their forward ends secured for tilting movement to a suspension frame, said suspension frame comprising a locking mechanism for locking the whole of ridging surface, carrying beam and cross elements in a fixed position relative to the suspension frame, the arrangement being such that, after unlocking, the fixed position is changed, the whole is tilted about the point of attachment in the suspension frame, and hence the height of the edge of the curved surface relative to the earth surface and the position of the noses of the ridging elements are changed.
  • said suspension frame is itself suspended in a set of suspension arms which are securable to a tractor or like vehicle for tilting movement relative thereto, wherein the suspension frame with ridging elements is movable in a substantially vertical plane, said suspension frame including a draught control handle for setting a desired minimum height of the suspension plane relative to the earth surface on which the tractor or other vehicle finds itself.
  • the apparatus according to the invention is productive of highly uniform ridges.
  • the apparatus is very suitable for use in conjunction with methods of "pulling" crops by means of rubber rollers, which methods are much used at present.
  • an inter-row rotary cultivator Secured behind a tractor or similar vehicle is an inter-row rotary cultivator, a draught setting wheel 1 of which is shown diagrammatically.
  • This implement comprises a carrying structure 2, which is conventional for such purposes and will not be described in any detail, and to which the inter-row rotary cultivator 3 is secured.
  • the cultivator 3 consists in essence of a plurality of tines 5, secured to, and around, a rotary shaft 4 to extend at an angle to each other.
  • the construction of such an inter-row rotary cultivator is well-known, and will not be described in any detail herein.
  • Secured to the carrying construction 2 behind the inter-row rotary cultivator 3 as viewed in the direction of advance of the tractor, is the ridging system which specifically forms part of the present invention.
  • the ridging system comprises a suspension frame 6 which by means of a set of suspension arms, of which arms 7 and 8 are shown, is secured to the carrying construction 2.
  • the suspension arm 7 is secured for pivoting or tilting movement about the end away from the suspension frame 6 to a beam 9 of the carrying structure 2, which beam extends substantially rearwardly.
  • the arm 7 is secured for pivoting or tilting movement to the suspension frame 6.
  • the suspension arm 8 is secured for pivoting or tilting movement, at one end to carrying structure 2, and at the other end to the suspension frame 6.
  • the suspension frame 6 consists, for example, of a pair of side plates 10 interconnected by beams. Each plate 10 is provided with a forwardly directed projecting part 11 and a rearwardly directed projecting part 12. Furthermore, a horizontally disposed plate 13, provided with an aperture in the horizontal plane, is secured to one or both side plates 10. Mounted in the internally threaded aperture in plate 13 is a threaded depth-stop handle 14. By turning the handle 14, it extends more or less deeply through that aperture. The lower end of handle 14 is in contact with a stop plate 15 fixedly secured to the carrying structure 2. Accordingly, by operating the handle 14 the position of the suspension frame with the parts secured to it can be varied relative to the carrying structure 2 in a substantially vertical plane.
  • the ridging system proper Suspended in the suspension frame 6 is the ridging system proper of the apparatus according to the invention.
  • the ridging system proper consists of a carrying beam 16 arranged transversely to the direction of advance of the tractor. On opposite sides of the carrying beam 16, cross-beams or cross-arms 17 are secured to it.
  • the combination of carrying beams 16 and cross-arms 17 is suspended in the suspension frame 6 for pivoting movement about the shaft 18.
  • the other end of cross-arms 17 is secured by means of a continuously variable locking mechanism 19 to the projecting part 12 of the side plate 10 of the suspension frame 6.
  • the setting of the ridging system proper relative to the suspension frame can be effected, for example, by means of an adjusting spindle 20, which operates similarly to the depth-stop handle 14.
  • the ridging elements Connected to the carrying beam 16 of the ridging system proper are the ridging elements, which are interconnected to one whole 21, each interconnection presenting a concave continuous surface merging into the ridging elements, so that the whole 21 can be described as a domed surface.
  • the noses 22 Forwardly at the bottom of the whole 21 are the noses 22, which point in the direction of advance of the apparatus.
  • a plate 25 Suspended under a beam 23 of the carrying structure 2, which beams extends transversely to the plane of the page, is a plate 25 rotatable about a shaft 24.
  • the plate 25 is shown to be in contact with the carrier beam 16, while the plate 25 is shown in the freely depending state in ghost outline. In operation, the tines 5 loosen and throw up soil. Partly owing to this, the plate 25 is pushed up into contact with the carrying beam 16.
  • Fig. 2 shows a front elevational view of the lower part of a portion of the domed surface 21.
  • the lower edge 26 of surface extends from the plane containing the noses 22 gradually upwards to a highest point located halfway between the noses 22.
  • the edge 26 determines the shape of the earth ridge formed between the noses 22.
  • a side face of the surface 21 is shown. Provided on that side face is a vertical sidewall 27, the plane of which is directed virtually in the direction in which the apparatus is advanced in operation, which sidewall adjoins a "half" ridging element 29.
  • Fig. 3 shows a cross-section, viewed from above, through a number of important parts of a portion of the apparatus shown in Fig. 1.
  • the shaft 4 of the inter-row rotary cultivator with the tines 5 attached thereto and the lower parts with the noses 22 of two ridging elements integrated into the domed surface 21. Extending between the noses 22 is the lower edge 26 of the surface 21.
  • the carrying beam 16 and the cover plate 25 are shown in ghost outline.
  • Fig. 4 shows the ridging system proper in a position tilted rather high about the shaft 18, and Fig. 5 shows the ridging system in a low position.
  • a front-elevational view of a bottom part of the surface 21 pertaining to the position shown in Fig. 4 is depicted in Fig. 6, while Fig. 7 shows a similar front elevation pertaining to the position shown iri Fig. 5.
  • Fig. 8 shows how the system operates if there is the danger that too much ground is thrown up by the ridging elements.
  • the tines 5 have become worn in use.
  • a worn tine is shown in broken lines.
  • the ridging system would also come to be in a lower position relative to the ground in the absence of suitable means.
  • the noses 22 of the ridging elements forming part of the continuously domed surface 21 would thus penetrate to an undesirably deep level into the soil, which is not loosened by the rotary cultivator and accordingly in compact condition.
  • the soil pressure will be increased, and push the ridging system upwards, via the pressure on the cover flap 25, until an equilibrium is set between the supply of soil and the soil passage capacity of the ridging system.
